DUMPING MECHANISM FOR VEHICLE-CONTAINERfi.

Specification of Letters Patent.

Patented Jan. 1, 1918.

Application filed September 5, 1916. Serial No. 118,439. I

dumping mechanisms for vehicle containers or wagon bodies.

One of the objects of my invention is to provide mechanism for dumping containers, or bodies of vehicles, which is easily operated, simple and inexpensive in construction and. which is so arranged that the container when returned to normal position is supported at four points, at least, on the frame without imposing all of its wei htupon the dumping mechanism, at any time.

Another object of my invention is to provide a dumping mechanism whereby the hopper, other receptacle, or body, is inseparably attached to the supporting frame, and another object is to provide an automatic lock, to restrain the mechanism, t0 prevent its movement when the receptacle is in its normal position.

Other and further objects of my invention will become readily apparent, to persons skilled in the art, from a consideration of the following description when taken in conjunction with the drawings, wherein Figure l is an end elevation of the device showing the hopper-like receptacle by dotted lines in dumping position, and by full lines in normal position. r

Fig. 2 is a side elevation showing parts in section.

In both views the same reference characters are employed to indicatesimilar parts.

In the particular embodiment illustrated herein, I have shown the dumping mechanism applied to a side dumping container and I have shown it adapted to be'dumped upon either side. It is evident, however, that the same mechanism may be employed for dumping the contents of the receptacle at the end or rear of the vehicle, in which event the dumping mechanism moves the hopper or body only in one direction, from its normal position.

The two end frames 5 and 6, which are substantially duplicates of each other, are mounted upon a base 7. Each end frame is provided with a rack 8, parallel with,

but below the slot 9. A semi-ovate Wing or frame 10 extends vertically from the frames 5 and 6 and through these wings, nearer to the respective body parts of theend frames, the slightly curved slot 9 is made. Extendinglaterally from the wing 10 is aflange 11 which substantially overlies or projects into a vertical plane including the outer edge of the rack 8. This flange aflords means for protecting the rack from falling dirt or dust.

; A hopper 12 is provided, at each end, with an outwardly extending flange 18 and is mounted upon a shaft 14k,v said shaft being located below. the center of gravity of said hopper. The shaft extends through the slots 9-9 and beyond theframes 5 and 6 and includeson each end a roller disk 15 and a geared pinion 16. The roller disks 1515 each tracks in a space between the rack 8 and the wing 10 on the flange 16. These rollers bear the weight ofthe-Ihopper or receptacle '12, when the said receptacle is being moved into dumping position. On

either'of the outer ends of the shaft 14 is a crank lever 17 for rotating the shaft in the act of dumping the contents of the receptacle 12. Located around the edge of the frame or wing 10 are a series of rollers 18,

19, 20 and 21. These rollers are preferably mounted upon arms 22 that are slidably adjustable between ribs 23. The rollers 19 and 20, of which there are two of each, one

at each end, underlie the flanges 13l3 of the hopper, or body, and support the outer corners of same when it is. in normal position, as shown by the full lines in Fig. 1. The hopper, or receptacle, cannot .be moved from this position of rest unless the shaft let be rotated. Projecting from the shaft 14, as an integral extension of the' crank ,arm'17, is an arm 24 pointed, at its outer end, and adapted to engage a spring latch .25. The spring latch bythis means holds the'shaft 14: against rotationwhile the receptacle, or hopper 12, is supported by the rollers 19 and 20 upon the frame or wing 10 ofthe end frames 5 and 6.

To dump the hopper it is only necessary to rotate the crank arm 17, after raising the latch 25 to permit the free rotation thereof. The dotted lines show that the crank arm 17 has rotated to the terminal of the slots 99 to the left and that the hopper 12 has moved into dumping position. In the particular exemplification shown, the hopper 12 may normal position, aeiaaeaea line'or" dump: .ingvposition, the flanges1313 of the hop perengagethe toners is or 21', asthecase may be, below a line"; drawn fthrough the transverse center of the hopper, when the hopper is in dumped -position, u causing: the

hopper to%ride upon" these guide rollersiu'ntilwit reaches a position where'the flanges as the c'asemay be, after which, upon further rotationiofthe crank arm 17 ,-the

hopper will be brought to upright-position as shown inTfull' lines in Fig; 1, with the flanges Il3f13 resting. upon the central, up-

ends of the flanges 13-18 resting:upo11-'tlie rollers 19 19 and 20-20, vthus holding the hopper firmly inplace, against possibility ofidisplac'ement, except by rotation of the crank arm '1-7' or the shaft 14. Theshaft 14L transmitstheipower from the crank arm from the frame- 5 to' a'gearedpinion 1-6,

which israssociate'd with-the frame 6 by dumping mechanism; Y shown in cross section on theieftsidedf Fig 2 is substantially duplicated *on theJright side, withthe exception that thecran k arm issho'wn on theleftside '-end=but*it" may as' conveniently be" located interchangeably omtheright side en'dof the shaft'elet;

The apparatu's?heretofore described shows how the mech anism 3 for dumping the vehicle arece'ptacle may be employed for dumping on either'oneor the other of the sides of the vehicle but it is manifest that without material change the same mechanism-may be employed foridumping the receptacle at the rear of 'the vehicle, when desired, in'which latter event the mechanismwill dump in one direction only.

endifi'ames, a rack on each frame; a receptacle positioned between the frames, a shaft extendingthrough the receptacle and journaled therein, a pinion on each end of the shaft in engagement with the adjacent racks, means for rotating the shaft, flanges projecting outwardly from each end of the receptacle and-positioned to bear upon the upper edges of the frames when the receptacle is in its norma-lzposition, and'rollers carriediby each frame for engagement with the flanges when the receptacle is moved from wnormal position.
